WINDOW-SASH.

SPECIFICATION forming `para of Letters Patent No. 276,416, dated April 24, 1883.

Application iled December 19, 1881. (No model.)

To all Iwhom tt may concern:

Be it known that I, BENJAMIN HUETUBES, of Rahway, in the State of New Jersey, have invented certain new and useful Improvements in N oiseless Sashes for Carriage or Gar Windows; and I do hereby declare that the following is a full description thereof, reference being had to the accompanying drawings, in which- Y Figure l is a side elevation, showing a carriage-window sash with my stit'ened rubber buffer applied. Fig. 2 is a horizontal crosssection of same. Fig. 3 is a side view, partly in section, through the buffer. Fig. et'is an edge view of Fig. 1. Fig. 5 is a horizontal cross -section through the buffer; Fig. 6, a similar section through the buii'er and one of its retaining-screws.A

One of the difficulties in making carriage window sashes is to avoid the noise, rattling, and jarring due to the contact between the edges ofthe sash and the edges of the grooves of the frame in which it plays.

My invention overcomes this dicult-y; and it consists in applying to each vertical edge of carriage or car window sashes a stiftened rubber buffer consisting of a attened rubber tube of suitable cross section closely surrounding a metallic bar or stiffener, so that two screws, one near each end, passing through the rubber buffer and its metallic stiftener, will rmly secure the same to the sash withoutimpairing the elasticity and noisepreventing qualities of the buffer.

A shows a carriagewindow sash; B, the frame in which it slides; C, the rubber buffer, which I prefer to have made of soft vulcanized rubber in the form of a tlat hollow tube having a quadrilateral cross-section, as shown in Figs. 2 and 5. Its width is equal to that of the edge ofthe sash, and its thickness is sufficient to give desired elasticity-ordinaril y from one-fourth to threefourths of an inch. In the center of this tube Gis tightly inserted the metallic stiffener D, of the same cross-section as the interior of tube G. TheV tubes C may be made in continuous tubes, and be cut to proper sash lengths'by the sash-finisher; or they may be mape of proper lengths for a sash, and the rubber (soft vulcanized) placed directly upon and around the stii'ener, either in long strips or in sash lengths, with the rubber covering the stift'euer at the ends as well as around the sides.

E are two screws securing my improved buffer to the sash. These screws pass clear through the rubber and are cou'ntersunk in the metal stift'ener. By my construction the rubber buffer is stiii'ened without sacrifice of elasticity, and the screw-heads are kept from Contact with the sashframe, thus securing for my invention a high degree of durability and freedom from noise, the sash being held iirml y in its frame withoutjar or rattling.

I am aware that a window-sash frame provided with semi-cylindrical grooves in its vertical edges, adapted toreceive one end ot' a strip of rubber held in the groove by a wooden strip inserted in it over the rubber, the wooden strip being held in the groove by screws, and the free end ofthe rubber strip being folded over the front face ofthe wooden strip and lying in the recess between the front face of thewooden strip and theframein which the sash slides, has heretofore been employed; butin this construction the free end ot' the rubber, not being secured, is liable to wrinkle and bind in the re,- cess in the frame in which the sash slides and the device become inoperative; and I am also aware that a flexible tube having a metal rod passing through it, and secured to a swinging door near its lower end, and acting as a weather-stri p, has heretofore been employed; and I therefore lay no claim to such inventions.

.I claim- As an improved article of manufacture, the

flat hollow tube C, quadrilateral in cross-section, and provided with the stiffener D, the tube and stifteher being secured together by screws and the whole adapted to be applied to a window sash, substantially as herein shown and described.

In testimony that I claim the vabove improvements in noiseless window-sashes I have hereunto set my hand this 15th day of November, A. D. 1880.
